The theory is that the acid/base balance of the body determines protein wasting; when the system is less acidic, less nitrogen is lost in the urine. I've been doubtful about this study's results, more nitrogen might have been lost in the stool, but I now find myself less skeptical.

What causes an increase in muscle mass? Ask a bodybuilder, he'll know. Testosterone.

AbstractPotassium deficiency produced different effects in the kidney of male or female mice. While in female, potassium deficiency caused a marked renal hypertrophy with no significant changes in testosterone-regulated enzymes, such as ornithine decarboxylase and β-glucuronidase, in the male the same treatment provoked a marked fall of these enzymes owing to a dramatic decrease in plasma testosterone. Potassium replenishment restored plasma testosterone and renal enzymatic activities. These results show for the first time, that potassium modulates circulatingtestosterone and suggest that this cation could exert an important regulatoryrole in controlling androgen actions

Again, potassium deficiency causing testosterone secretion to decrease in male animals. Female animals proper hormonal balance involves less testosterone secretion than males does; the lower potassium intake in this study was more within their homeostatic range, so that the effect on testosterone in the female mice was lessened.

Again, anybody reading this do not I repeat do not potassium-load. Include foods that are not potassium depleted (that is, non-refined foods) in your diet. If your testosterone levels are low, it seems to me that you may be potassium-deficient.

Healthline just designed a virtual guide explaining how testosterone affects the body. You can see the infographic here: http://www.healthline.com/health/low-testosterone/effects-on-body

This is valuable med-reviewed information that can help a man understand how affects multiple parts of their bodies and the side effects that occur from having low testosterone. I thought this would be of interest to your audience, and I’m writing to see if you would include this as a resource on your page: http://naivenutrition.blogspot.com/2010/03/does-potassium-control-testosterone.html

If you do not believe this would be a good fit for a resource on your site, even sharing this on your social communities would be a great alternative to help get the word out.

Thanks so much for taking the time to review. Please let me know your thoughts and if I can answer any questions for you.
